6 - SOUND QUALITY OPTIMIZATION
- Warm-up sonic effect.
If the power amplifiers have not been powered on for a few days, the optimum sound quality is
reached after 15 minutes. This delay has been optimized to be minimal and the sonic quality when just
powered on is much higher than other quality power amplifiers.
- Speaker polarity.
Even if you have an absolute phase inverter on your preamplifier (as on the GOLDMUND MIMESIS
2+, MIMESIS 22M, MIMESIS 7.5), and even if you have carefully selected the proper line phase (see
in next paragraph), there is a possibility to again increase the sonic quality of your speakers by
reverting the polarity of both speaker cables at amp termination. But since the line phase and the
speaker polarity interfere to each other, you have to experiment carefully all the combinations before
picking the right one.
If your preamplifier has an absolute phase inverter, this will interfere too. If it has not, don't forget the
result will depend of the source, most of the record and CD being recorded without care for the
absolute phase. Be patient…
- Mains line phase inversion.
The sonic quality of your MIMESIS SRM2.3 can be greatly improved if the mains AC line is properly
connected. Try to invert the AC plugs of both your amplifiers, using special adapters.
We recommend that you proceed carefully to try this. You must do it in combination with the speaker
polarity and/or with absolute phase switching to be sure of the best result.
